Wiring some receptacles 220V for equipment, good idea or not?

New HT wiring is beginning and I am having a sub panel installed Monday with 4 20 amp circuits to power equipment. I remembered that 220V supply is balanced so the noise is significantly reduced vs a 120V circuit. My amplifiers can run either 120V or 220V so I am considering powering each on its own 220V circuit.

My 120V equipment runs trough an Exactpower unit that is plugged into an Olympus Mh-787 medical grade isolation transformer. http://hometheaterhifi.com/volume_11...r-11-2004.html

Is 220V a good idea or not? Where would I find new 220V power cords for my amps?

Seek out an electrical wholesaler in your area. Go in person. They will have multiple choices online for power cords/ cord caps for your amplifiers. Home Depot etc. might be overwhelmed with your request. Hope this helps.

Have a look here for power cords:

You can also have them custom built to your desired configuration.

Well, I'm no expert, but I don't see the disadvantages of using the 220V, you'll get a boost in power efficiency which may or may not matter to you?

Wire for a single 240 volt 30A. Use a step down transformer wired then to UPS. Won't necessarily reduce all hums, but it helps.
